The shelters are being purchased from Handi Hut Inc., of Cifton, N.J., and installed by Fast Signs Inc., of Allentown.

The installation, however, will take some time, officials said, because the proposed location of each shelter must be approved by the municipality in which it will be placed, officials said.

The positioning of each shelter must also take into account the existence of utility cables and pipes, pedestrian safety, the effect on sight lines for motorists at nearby intersections and the requirements of the Americans with Disabilities Act. Electricity must also be run to each shelter for nighttime lighting.

Ten shelters have already been installed in Upper Macungie Twp., Lehigh Co., said LANTA, which is currently working to install nine shelters in Allentown, 11 in Bethlehem and 20 in Easton. Installation of those shelters will complete 25 percent of LANTA's program, officials said.
